Definitions

  • the present invention relates to an incineration apparatus. More particularly, the present invention relates to a high-temperature pyrolysis incineration apparatus that incinerates general household waste or industrial waste at a high temperature.
  • an incineration method is generally performed with a method of burning waste that is collected and carried from each place together with fuel with large scale equipment, and dumping resulting ash.
  • an initial equipment cost of such a large incineration facility is enormous and a great deal of operation management cost is required, and a collection and transport problem and a processing problem of the remaining ash after incineration additionally occur.
  • a small-scale industrial waste processing apparatus that can be moveably installed has been in the spotlight, and particularly, a low-temperature pyrolysis incineration apparatus that is developed as a result of research on processing of special waste in which incineration processing should be performed, such as medical waste and industrial waste, is put to practical use.
  • Korean Utility Model Registration No. 20-0256297 is an example of the above-described low-temperature pyrolysis incineration apparatus, and discloses a low-temperature pyrolysis apparatus of a combustible gas using industrial waste as a main fuel.
  • the low-temperature pyrolysis incineration apparatus vaporizes a carbon material of industrial waste by pyrolyzing various waste tires or industrial waste at a low temperature in a main body of a carbonization device, and completely burns the industrial waste by supplying a gas to a combustion chamber through an induction pipe while continuously generating a gas that can use as a fuel, thereby processing without discharge of an air pollution material.
  • a low-temperature pyrolysis incineration apparatus of the above-described configuration has a drawback that an exhaust gas heavily occurs while a combustion chamber is often overheated when burning a chemical product such as vinyl and plastic, and because waste having a high moisture content is incompletely burned, the waste having a high moisture content should be burned separately from waste in a dry state.
  • the present inventor has suggested an apparatus that can pyrolyze at a high temperature as an incineration apparatus that solves the problem.
  • Korean Patent No. 10-1483751 relates to a high-temperature pyrolysis incineration apparatus that is suggested by the present inventor and that is registered as a patent, and because the high-temperature pyrolysis incineration apparatus has a configuration of injecting an incineration material into an internal combustion chamber, starting combustion in a closed and sealed state to be isolated from the outside, and performing high temperature combustion while forcibly supplying outside air upon combustion, the high-temperature pyrolysis incineration apparatus may incinerate an incineration material by complete combustion in a high temperature state.
  • the high-temperature pyrolysis incineration apparatus is small scale equipment that can be easily moved and that burns an incineration material at a high temperature by forcedly injecting air necessary for combustion to a space that is separated from the outside, and the high-temperature pyrolysis incineration apparatus has a merit that it can completely burn general household waste or industrial waste, but because the high-temperature pyrolysis incineration apparatus has a structure in which a blast pipe is disposed along an interior circumference of a combustion chamber, an area of the combustion chamber is relatively small and thus the high-temperature pyrolysis incineration apparatus has a small processing capacity, compared with an external form size.
  • the high-temperature pyrolysis incineration apparatus By embedding a heat exchange pipe within a wall body of the combustion chamber, the high-temperature pyrolysis incineration apparatus has a structure that recovers heat of hot air or hot water to be discarded, and thus a wall of the combustion chamber has a large thickness and a heavy weight.
  • the present invention has been made in an effort to provide a high-temperature pyrolysis incineration apparatus that is improved into a configuration that minimizes encroachment of an internal area of a combustion chamber due to installation of a blast pipe in order to solve a structural problem of a high-temperature pyrolysis incineration apparatus of Korean Patent No. 10-1483751 that is suggested by the present applicant, reducing a wall thickness by improving recovery of waste heat that is normally discarded through a lid of the combustion chamber, and completely burning an incineration material without a non-combustion residue in a short time.
  • An exemplary embodiment of the present invention provides a high-temperature pyrolysis incineration apparatus that forcedly supplies external air to a combustion chamber while burning an incineration processing material that is injected therein at a high temperature within a combustion chamber that is isolated from the outside, wherein an air-supply tube is fixedly disposed at the center of the combustion chamber, a fuel supply pipe is installed at an upper edge of the inside of the combustion chamber, the bottom of a lower portion thereof is formed with a punching plate for discharging ash that is generated by combustion to the outside, a stirring rod rotating using the air-supply tube as a fixing shaft is disposed at the center of the bottom thereof, a heat recovery device is disposed at one side of the outside of the combustion chamber, and a circulation pipe is extended from one side of the lid of the combustion chamber to the outside to return to a location corresponding to an upper portion of the stirring rod at a wall of the combustion chamber via the inside of the heat recovery device.
  • a plurality of holes are provided to enable the stirring rod to have a light weight, and a contour of the upper and lower sides is formed in a wave shape, such that while stirring, an incineration processing material uniformly contacts air instead of being cornered to one side to be completely burned in a short time.
  • a ball valve in a circulation pipe that is extended from a lid of an upper portion of the combustion chamber to a heat recovery device, when the lid is opened, a passage of the circulation pipe is automatically closed and thus external air does not enter into the heat recovery device.
  • the internal temperature of the combustion chamber may not be lowered to 800° C. or less.
  • a high-temperature pyrolysis incineration apparatus that is suggested in the present invention, as an air-supply tube is disposed at the center of a combustion chamber, an area occupied by a combustion space is minimized and thus processing capacity becomes large, compared with an external form.
  • Air that is forcedly injected through a ventilation fan is ejected from an air-supply hole of three steps of a high portion, a middle portion, and a lower portion to the air-supply tube of the center of the combustion chamber, and a lower portion, and thus air necessary for combustion can be fully supplied to a corner of the combustion chamber.
  • the high-temperature pyrolysis incineration apparatus can completely burn the incineration processing material without a combustion residue.
  • a circulation pipe that is extended from one side of a lid to the outside circulates a combustion gas in which waste heat is recovered via the inside of a heat recovery device to return again to a lower portion of the combustion chamber and thus a thermal loss is minimized, whereby a waste heat recovery rate is excellent.
  • a circulation pipe that is extended to a heat recovery device is automatically blocked and thus waste heat is not leaked from the heat recovery device to the inside of the lid, whereby an operator can safely reload an incineration processing material into a combustion chamber.
  • a controller when combustion is performed within a combustion chamber, if an internal temperature thereof is measured to be less than 800° C., a controller has a configuration for operating a pump of a fuel supply device and thus when burning an incineration processing material, an internal temperature of the combustion chamber is maintained at a temperature range in which dioxins do not occur and thus there is a merit that dioxins are not discharged into the air.

As shown in FIG. 2 , at a location that divides an external circumference thereof into a high portion, a middle portion, and a lower portion, a plurality of air-supply holes 16 are formed along an external circumferential surface, and thus the air-supply tube 10 may supply air to an entire region of a circumferential direction at a location of a high portion, a middle portion, and a lower portion of the combustion chamber 2 .

  • a high-temperature pyrolysis incineration apparatus having the foregoing configuration, by operating the pneumatic pressure cylinder 46 , the lid 12 is opened and an incineration processing material is injected, and in a closed and sealing state in which the lid 12 is closed again, when forcibly transferring external air into the combustion chamber 2 by operating the ventilation fan 26 , the outside air is ejected in a circumferential direction from the air-supply tube 10 of the center of the combustion chamber 2 through the air-supply hole 16 that is divided into a high portion, a middle portion, and a lower portion and is uniformly distributed to a corner of the inside of the combustion chamber 2 .
  • the ventilation fan 26 While incinerating an incineration processing material, the ventilation fan 26 continuously transfers outside air, and fuel supply through the fuel supply pipe 14 is continued until an internal temperature of the combustion chamber 2 becomes 800° C. or more.
  • the stirring rod 30 While incineration is started within the combustion chamber 2 , the stirring rod 30 starts a rotation, stirs an injected incineration processing material, and enables the incineration processing material to be evenly exposed to fuel and air, thereby enabling the incineration processing material to be completely burned in a short time.
  • an incineration processing material particularly, an incineration processing material having a high moisture content, such as food, vegetable trash, an animal body, a diaper, and medical waste
  • the incineration processing material is stacked at the bottom of the combustion chamber 2 by a self-load and thus when the internal incineration processing material is not burned, the stirring rod 30 mixes the incineration processing material to enable the internal unburned incineration processing material to be exposed to fuel and air and thus enables even an incineration processing material having a high moisture content to be completely burned in a short time.
  • an air curtain is formed in three layers of a high portion, a middle portion, and a lower portion.
  • the air curtain of three layers suppresses divergence of heat occurring when incinerating an incineration processing material, a temperature of a combustion region rises to a high temperature of 1200° C. in a short time and thus the incineration processing material is clearly incinerated without incomplete combustion, and a vinyl or plastic product as well as an incineration processing material having a high moisture content is completely burned without occurrence of an exhaust gas.
  • the high-temperature pyrolysis incineration apparatus is an environmentally-friendly incineration processing apparatus having no environment contamination that can originally block discharge of a harmful material and an exhaust gas, and because an incineration processing material is completely burned in a short time with incineration at a high temperature, a one-day processing capacity is remarkably increased, compared with an apparatus size, and thus the high-temperature pyrolysis incineration apparatus can be efficiently used.
  • the ball valve 52 automatically blocks the circulation pipe 48 and hot air that is supplied to the heat recovery device 4 does not thus move backward to the inside of the lid 12 , so when an incineration processing material is reinjected, the operator does not suffer burns by hot air.
